How I do I get this guy to notice me in the span of a month?! HELP please?

alright so there's is this guy that is really cute and adorable and I happen to be interested in him and would want something casual and light, kinda like a summer fling because we'll only be around each other for a month. We've seen each other around and its been awkward but we've only started talking recently and I was wondering what to do, short of throwing myself at him, but some obvious flirting tricks that might win him over asap, thanks!
